Overview HD-SDI (SMPTE 292M) is the primary interface worldwide for High Definition digital uncompressed video. Its bit rate is 1.485 Gbps. This standard evolved from SD-SDI, which supports standard resolution only and is defined by SMPTE as SMPTE 259M. This card supports both standards. The VidPort SD/HD™ is a single channel HD/SD-SDI card with a single lane PCI Express (PCIe) bus interface. It converts to a transmitter or receiver card with a firmware change. The VidPort SD/HD receives or transmits one HD/SD-SDI stream and transfers the descrambled stream to/from the system memory via the PCIe bus. On board memory and a proprietary firmware design are used to buffer the inputs to account for system latency as the data flows to the PCIe bus. When the card is in the receiver mode, the clock and data recovery block locks onto the incoming signal. Once locked, the card then deserializes, converts from NRZI to NRZ, descrambles and frames the stream into 10-bit words before writing the frame to on board memory. The card also supports de-interlacing in the hardware and can monitor the incoming stream for CRC errors. After each frame is written to the on board memory, the card then transfers the frame to the system over the PCIe bus. The transmit stream can be synchronized with other HD/SDSDI streams for switching, editing and overlays. At this time, this card is targeted at OEMs who are building video servers, video encoders, and video capture systems. Later on we plan to introduce applications… and are interested in licensing yours if you have one!

Indicator LEDs – Indicator LEDs are provided on the bracket to show receiver or transmitter operation. The LEDs flash to indicate when valid data is received or transmitted. When the channel is not in operation, the LED will be on if a carrier is detected.
Software Support
Windows® 7 32 and 64 bit, Windows® XP, Windows® Server 2003, and Windows® Server 2008 driver, API, and sample applications support
Linux® driver, API, and sample applications support
DirectShow® SDK o Source and Sink Filter Interface o Interface to WME o Support for GraphEdit o Support for Direct X
We have a DirectShow® filter we call the Sink Filter, which provides an interface to the Vidport SD/HD driver. The recommended input is a single program MPEG-2 transport stream at its input pin, although it will accept other formats. We also provide a sample application with source code that shows how to interface to the Sink Filter.
